OUTLAST HOUSTON : event overview

OUTLAST Houston is a trail endurance challenge in Navasota, Texas (18135 FM-362) held February 20–21, 2027. The format requires runners to complete a 5K loop every hour; each lap must be finished within the hour to remain in the event. Participants who miss a lap are removed from further rounds.

The event is offered in three formats:

  • 6 Hour Challenge - 18 Miles
  • Outlast ULTRA 12 Hour Challenge - 36 Miles
  • Outlast ULTRA 24 Hour Challenge - 72 Miles

Each 5K lap is timed individually. Runners who complete all laps in their chosen event have a combined time that counts toward local results and the world leaderboard. Top male and female finishers in each event are recognized with a 1st Place OUTLAST award.

Terrain is trail-based with natural surface, elevation, and unpredictable conditions; some sections may include pavement or gravel. Aid at basecamp/loop start provides water, basic hydration, and snacks; the event is cupless so participants should bring their own bottle or hydration system. Participants may walk as long as each 5K is finished within the hour. Tent or personal aid station setups are allowed at the venue.

Awards and recognition include patches for partial completion, premium medals or a buckle for full finishers according to the chosen event, a premium OUTLAST T-shirt for all participants, ranking on the world leaderboard, and cash prizes associated with the season and championship events.
